Anaximander (611?-547? BC), Greek
philosopher, mathematician, and astronomer, born in Miletus in what is now Turkey.
He was a disciple and friend of Greek philosopher Thales. Anaximander is credited
with having discovered the angle at which the plane of the ecliptic is inclined
to the celestial equator. He also introduced the sundial into Greece and invented
cartography. Anaximander's outstanding contribution was his authorship of the
earliest prose work concerning the cosmos and the origins of life.
